PCB 3063 Exam 1
What are the similarities between human and bacterial DNA? - ✔️✔️double stranded,
universal genetic code

translation - ✔️✔️genetic information coded in mRNA directs formation of a specific
protein at a ribosome in the cytoplasm


1970s - ✔️✔️DNA cloning tech tools to understand human genome

genomics - ✔️✔️sequencing human genome

bioinformatics - ✔️✔️molecular biology and computer science

Francis Crick - ✔️✔️central dogma, DNA - RNA - protein

model organisms - ✔️✔️short generations, large progeny, adapt to lab,
inexpensiveness to maintain

1953 - ✔️✔️Watson & Crick

PCR - ✔️✔️1980s, replaced time consuming techniques

1990 - ✔️✔️human genome project

1995 - ✔️✔️first full DNA sequence (bacteria)

Junk DNA - ✔️✔️false theory that says 95% of genome does nothing

Epigenetics - ✔️✔️changes expression with out sequence changes, can be inherited

CRISPR - ✔️✔️editing genome, simplifies process

prokaryotes - ✔️✔️unicellular, one compartment

eukaryotic - ✔️✔️compartmentalization into organelles

eubacteria - ✔️✔️true bacteria, e. coli

archaea - ✔️✔️ancient bacteria, more similar yo eukaryotes

, nucleus - ✔️✔️separates DNA from other cellular components

transcription - ✔️✔️DNA sequence in a gene is copied into mRNA


what are chromosomes made of? - ✔️✔️1/2 DNA 1/2 protein

chromatin - ✔️✔️genetic material when cell is not dividing

histones - ✔️✔️protein, organization and condensing of DNA

virus - ✔️✔️not living organism, nucleic acids wrapped in protein

plasmids - ✔️✔️mini chromosome, drug resistance genes, common in bacteria

nuclear matrix - ✔️✔️protein system organizes DNA

somatic cells - ✔️✔️not for gametes, mitosis, diploid

homologous pair - ✔️✔️carry same set of genes, similar in size and structure

alleles - ✔️✔️different versions of a gene

centromere - ✔️✔️attachment site of spindle microtubules, dictated by DNA

metacentric - ✔️✔️

submetacentric - ✔️✔️

acrocentric - ✔️✔️

telocentric - ✔️✔️

kinetochore - ✔️✔️multiprotein complex assembles on centromere, facilitates
attachment

telomeres - ✔️✔️structure on end of chromosome

somatic cell cycle - ✔️✔️interphase, mitosis

interphase - ✔️✔️G1 - growth, S - DNA replication, G2 - prepare for mitosis

mitosis - ✔️✔️prophase, prometaphase, metaphase, anaphase, telophase, cytokinesis
